Running your own business means doing your own maths. Day rates, tax estimates, late payment interest, cash flow gaps — it's relentless.
We built these tools because we got tired of searching for them. They're all free, work in your browser, and don't require an account. Your data stays on your device.
Work out what you should charge per day based on your target annual income, working days, tax, expenses, and profit margin. Probably the most-used freelancer calculator in the UK.
Enter your income and expenses. Get a full breakdown of Income Tax, Class 2 and Class 4 National Insurance, student loan repayments, and your actual take-home pay.
Calculate what a client owes you in statutory interest and compensation under UK law. The Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge interest on overdue invoices — most freelancers don't know this.
Plan your income and expenses month by month for 3, 6, or 12 months ahead. Spot cash gaps before they happen. Export to CSV for your accountant or records.
Track expenses by HMRC category throughout the year. See your spending breakdown by category, running totals, and export to CSV when tax return time arrives. Uses localStorage — your data stays in your browser.
Calculate your HMRC-approved mileage claim for cars, vans, motorcycles, and bicycles. See your actual tax saving based on your tax rate.
Create a professional-looking invoice, preview it, and download as PDF. Includes VAT toggle, multiple line items, and all the fields HMRC expects to see. No account needed.
Generate chase emails for overdue invoices at three escalation levels: friendly reminder, firm follow-up, and final notice. Copy-paste ready with the right tone for each stage.
Track clients, projects, and invoices in one place. Dashboard shows active clients, outstanding invoices, revenue collected, and average days to payment. Export per section to CSV.
Find out if Making Tax Digital affects you, what software you need, your deadlines, and a personalised action plan. Takes 2 minutes. The MTD deadline for incomes over £50k is 6 April 2026 — 22 days away.
Because freelancers already pay for enough software. These tools cover the basics that shouldn't require a monthly subscription. If you want more — step-by-step guides, template packs, escalation systems — we sell those separately. But the tools? Free. Always.
If you find the free tools useful, we also sell practical resource packs for common freelancer problems:
The Getting-Paid Toolkit bundles invoice templates, chase email sequences, contract clauses, and compliance checklists into one download. Stop piecing it together from free tools.
